    Smardt Chiller Repair - Turbocor

    This was my first repair on a turbocor compressor. The IGV on compressor #1 stop responding.......couple months later compressor #2 IGV stop responding and got stuck in a fixed position just like #1 compressor. We talked to DTC they said there was a problem with some of the IGVs installed on some of the ealier compressors. Just finished up the repair today...... compressors came online and loaded up correctly.

    Looks good. What was the problem with the IGV? What year was the compressor built?

    The IGV was stuck at 20% it would not open or close.

    I just realized I posted in the wall of shame Can someone move it to the commercial forum.

    I was wondering why this was in the HOS! Ping one of the moderators, they can move it for you.

    Did the ball bearing in the peep window indicate that it was stuck at 20% Or did it move the full 0-100 range? Did the IGV test ok?
